Credit card nickname
I would like to name my credit cards ("Irl's AMEX", "B's auto Visa"). Safari allows this but Firefox doesn't seem to. Or at least I can't find it. Basically, when I view a saved credit card, instead of seeing, e.g., "****1234 2025-01" I'd like to see a text entry which I can edit. I'm even willing to do a bit of fancy footwork (add something to the .plist, say). OS X High Sierra, 10.13.6.
